MUFFLING- SYSTEM FOR EXPLOSION-ENGINES.

To all whom it may concern` Be it known that I, ALEXANDER WINTON, acitizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Mutlling Systems for Explosion-Engines, of which thefollowing is a specification, reference being had therein to theaccompanying drawing.

My invention relates to improvements in mnftling systems for explosionengines, the object of which is to make an effective and cool maillingsystem especially intended for motor boats using explosion engines.

In the accompanying drawings Figure 1 is a side elevation of a portionof an explosion engine showing the improved system applied thereto. Fig.2 is an end elevation showing theexhaust pot in section. Fig. 3 is avertical section of the exhaust pot, the section taken at right anglesto that shown in Fig. 2. Fig. 4 is a cross sectional view on the line1-4 of Fig. 3, looking in the direction indicated by arrow.

Referring now to the drawings7 1 indicates the cylinders of an explosionengine, 2 the water inlet pipe which is connected with the cylinders inany suitable manner for circulating cool water around the explosive endsof the cylinders, and as here shown connection is made by a plurality oflateral pipes or connections 3. A pipe 4t is the outlet pipe for thewater after it has circulated around the cylinders and this pipe isconnected with the cylinders by lateral passages, connections or pipes5. A suitable manifold 6 is connected with a carbureter (not shown) andwith the explosion ends of the cylinders in the usual way to furnish theexplosive mixture. Thus far `only the ordinary construction of explosionengines has been described and the present improvement will now e setforth.

Extending across the sides of the cylinders 1, is an exhaust pocket 7,which receives the exhaust from the cylinders 1. This exhaust pocket isconnected with a vertically arranged exhaust pot 8 through the medium ofa pipe or connection 9. This pipe or connection 9 extends upward withinthe exhaust pot 8, as shownat 10 and has its upper end doubled andextends downward, as

shown at 11, thus constituting an inverted U-shaped upper end. Locatedwithin this pot and below the outlet end 12 of the pipe Specification ofLetters Patent.

l() is a diaphragm or baille partition 13, which partially closes thepot 8. This partition 13 is inclined, as shown in Fig. 3, and theexhaust gases from the .motor are projected from the end 12 against thisbaille pla-te or partition, which diffuses the gases within the pot andprevents them from being projected straight downward therein. The lowerend of the pot 8 is provided with the out-let pipe 11i, which has itsinner end 15 extending downward within the pot and its outer endextended outward. This outer end will extend to the outside of the hullof the `vessel (not shown) in any suitable manner and in any suitablerelation to the sea level. An adjustable gate valve 16 is located withinthis pipe 111-, for the purpose of varying the sizes of the outlet asdesired. The upper' end of the pot 8 has an outlet 17, and this outletis provided with a gate valve (not shown) of the saine form as t-he gatevalve 16, and is adjustable through the medium of a suitable wheel 18.This gate valve controls the passage of the exhaust gases from the potS, through the pipe 19, which pipe will extend into the ventilator stack(not shown) of the vessel.

The lower end of the pot 8 will be so l0- cated in the boat that theinner end 15 of the pipe 1st will be below the sea level, although thismay be higher or lower, though, preferably, as shown. The water outletpipe 4, from the water circulating system of the engine passes into theupper portion of the pot S, through the pipe 20, and this connection ispreferably located above the exit end 1Q, through which the exhaustgases enter into the pot. From this it will be understood that thecirculating water from the engine passes into this pot and finds itsoutlet through the pipe 14. The circulating water passing into the potserves to cool the exhaust gases and the pot and this is increased byreason ot the exhaust outlet 12 being below the water inlet 20. By meansof the two gate valves 16 and 17,`they can be adjusted so that theexhaust may fully or partially pass through the Ventilating stack. Withthe gate valve 17 closed and the valve 16 at sea level open, all theexhaust finds its exit close to or below the water line as desired. Inpractice, preferably the top valve 17, is left partially open and themajor portion of the exhaust escapes under water. Upon stopping theengine there is no back siphon action as the top valve is open and thereis no tendency to vacuum by reason of condensation or cool ing of theexhaust pot. The effect of the combination is a cool noiseless exhaust.

Having thus deseribedthe invention, what is claimed and desired tosecure by Letters Patent isl. The combination with an explosion engine,having a common manifold, of an exhaust pot in Communication with saidmanifold, the said exhaust pot having an outlet in its upper and also inits lower end, a water circulating cooling system for the engine havingcommunication with the exhaust pot at a point between the two saidoutlets, valves for operating said outlets, whereby the exhaust gasesmay be passed out of the upper opening and the water out of the loweropening or both the exhaust gas and water together out of the lower ofsaid openings, the water circulation through the said pot not beingdisturbed in either event.

2. The combination with an explosion engine, having a Common exhaustmanifold, of an exhaust pot having communication with said manifold,said communication comprising a virtually inverted U-shaped tube havingits lower end in communication with the exhaust manifold and its upperend open and within the exhaust pot, a baffle plate arranged below theexhaust inlet into the said pot, said'pot having outlets in its upperand lower ends and valves for opening and closing said outlets for thepurpose 'described.
